Application led July l,

To all 'whom t may concern.' n Be it known that l, ARTHUR ADAMS, a citizen of the United States, residing at Baltimore city, State of Maryland, have invented certain new and useful improvements in Stump Pullers, of which the following is a specification. y i i This invention relates to stump pullers and `has special reference `to a portable stump puller designed for operation by horse or man power or the like.

@ne important object of the invention is' to, improve the general construction of devices of this character.

A; second important object of the inveir tion is to provide an improved portable stump puller wherein the pulling mechanism may be shifted about a vertical axis to any desired angular relation with the supporting mechanism.

A third important object of the invention is'the provision of improved means for raising the pulling mechanism to elevated position while turning on said axis.

A fourth importa-nt object of the inventionis the provision of a novel winding drum arrangement in such a machine designed to effect a pull back movement of the stump cable and stump.

lWith the above and other Iobjects in view s as will be hereinafter apparent, the invention consists in general of certain novel dv tails of construction and combinations of parts hereinafter fully described,`illustrated in the accompanying drawings and speciii cally claimed.

In the accompanying` drawings like characters of reference indicate like parts in the several views, and:

1924.-. Serial No. 723,460;

Figure 10 is a side view of the operating lever for the elevating mechanism and its connections.

Figure 11is a diagram showing the manner of pulling a stump with this device.

The mechanism of the invention is mounted on a platform 10 which `is supported between a pair of hollow, box like sled runners 11, the platform being turned up at its ends `to prevent digging `into the ground. There is thus provided in the support, a central well and in this well is mounted a vertically movable short cylinder 12 having a diaphragm or base plate 13 extending thereacross, vthe base plate being provided with an annular groove forming a ball race for the bearing ballsg11l. Beneath this base plate 13 are provided pairs of links 15 which have their lower ends pivotally connected to lugs 16 fined to the platform 10. The upper ends of each pair of links are connected by a tie bar 17;" These tie bars 17 are connected at one end of eachv by across bar 18 and on these bars rests the base plate 13. By an inspection of Figure 3 it will be seen that movement of said tie bars to the left in that ligure will effect elevation of the base plate.

In order to so move the tie bars the cross bar 18 has connected thereto one end of a link 19 which extends outwardly through one of the runners and has its outer end connected to one arm 2O of a toggle or elbow joint, said arm being pivoted at one 'end to a lug `21 fixed to the side of the runner. So the other end of this arm 20 is pivoted on one end of a second toggle arm 22 the remaining end of which is pivoted to a rod 23 movableslidably throughguides 24 fixed to said runners.` Theremainingend-of this rod is linked to a hand lever 25 which has its lower end pivoted in turn to the runner. By ihismeans movement ofthe hand lever will effect raising or permit dropping of the base plate in accordano-i with the direction of such n'iover'nent.A

@n the ballsllA supported a turntable 26 which isheld in the `upper end of the cylinder 12 and on this turn table is mounted the main frame ofthe machine which includes lower longitudinal angle bars 27 and upper longitudinal angle bars 28 con-` nected `at their extremities by corner posts 29. At their central parts the bars 27 are connected by a transverse` member 8O in which is journalled the lower end of a vertical .shaft 31 `preferably having its lower lv OO part square in cross section. Carried by the upper bars 28 is a housing' 32 concentric with the shaft 3l and mounted on this shaft is a lower clutch member 33 which lits in 5 the housing' 32 which tlius-'liorms'an upper bearing for said shatt. is in the form of a toothed tace clutch and `cooperates with an upper clutch member 23st. The upper clutch member is slidably in mountedv for. vertical.iiioveinenton rods provided. with ,heads 3G. which rest on. the top of the housing' 32, the. clutch being guided, in vertical movement by .tlie'litting l5. 31 on'y whichit maybothv slide and rotatie. f'llie .rods 35 are also provided with offset lieadshaving journalportiensBS. ivliereto lare pivotedthe upper ends of: links 39.

Carried by the upper clutch A member is. a. sweep ll by means rof which theaipper ymember`r may be rotated.

. On the upper andilower end oi the squared portion ot the. shatt .3l are..mouiit1ed the mi gears. ft2, the upper gear `beingypart of the lower clutch member. These gears mesh with idler gears Ll-S'carried by a .vertical shaft stel and. the gears 13 nieshrin tiiriifwith thegears tixed on; a vertical drum shat't :l5 iti carrying a vertical stuiiip pull ing druiii in'iilarly thcgotl-iei.' end ot the trame- .is provided with a veiticat drum `shatt t8 whereoniis mounted zii-bauliiig'lor pull 4bark drinn-4S).
